    The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission is a planned two-year mission funded at $242 million (not including launch costs) and targeted to launch in 2023.

    As far as The James Webb Space Telescope goes...

    I love the idea of this idea of building a large radio telescope on the far side of the moon. It's obviously a great idea because the far side of the moon is the best place to get away from all the Earth's background noise. It's also a relatively simple thing to construct and we could gain great insight into the problems of construction in low gravity.


    I like the fact they have chosen a rover design that's over 10 years old, so probably fairly robust and would not need a lot of R&D to convert it into machines so they can erect the telescope. The DuAxel Rovers are designed to split up so the front section can roll down steep inclines.

    More geeky stuff here: https://trs.jpl.nasa.gov/bitstream/handle/2014/42763/12-0929_A1b.pdf?sequence=1

    So it looks like you set down a lander that has the central core of the telescope, an expandable mesh and a few of these little rovers. The rovers wheel up to the top of the crater and the front half secures it's self to the ground while the front section goes back down the crater walls. When back at the lander it will connect to the cables needed to expand the telescope and the anchored front section will pull up the cable.

    Sounds like a nice simple plan and if you can create anchor points without sacrificing the front half, then you can send the rovers off to explore the area nearby.

    I believe that it's in the proposal stages at the moment but I hope it gets green lit.
